Sixty-three mother-toddler dyads took part in a 6-month prospective study that examined how differences in the frequency and nature of early mother-toddler conflict related to individual differences in children's subsequent socioemotional development. When the children were 30 months, mothers and children participated in a series of laboratory tasks and in a 1.5-hr unstructured home observation. All episodes of verbal conflict between mothers and their children were identified from these sessions, transcribed, and coded for certain elements (e.g., strategy, discussion of emotion, and resolution). At 36 months, children participated in measures of emotional understanding, social competence, and early conscience development. Mothers' use of justification, resolution, and mitigation in conflict at 30 months predicted high levels of socioemotional development at age 3. These findings suggest that conflict may be an important context for children's socioemotional development. 相似文献

The onset and development of preschoolers' awareness of sex role stereotypes, gender labeling, gender identity, and sex-typed toy preference were explored in 26-, 31-, and 36-month-old children. Gender labeling, gender identity, sex-typed toy preferences, and awareness of adult sex role differences were observed in significantly more 26-month-old children than would have been expected by chance. Verbal gender labeling was observed in a majority of 26-month-olds, while verbal and nonverbal gender identity were observed in a majority of 31-month-olds. Nonverbal gender labeling and awareness of adult sex role differences were observed in a majority of children by 36 months. No evidence of awareness of sex differences in children's toys was found in the majority of children at any age. Awareness of sex role differences in children's toys was not related to awareness of adult sex role differences. Brighter children were more aware of adult sex role differences. Sex-typed toy preference was not related to awareness of sex role differences but was related to gender identity. Predictors of sex role development included the mothers' employment, and the father's personality traits, attitudes toward women, and sex-typed activities in the home. Implications for theories of early sex role development are discussed. 相似文献

Does strategy knowledge influence working memory in children with mathematical disabilities? 总被引：12，自引：0，他引：12
This study investigated the relationship between working memory (WM), declarative strategy knowledge, and math achievement in children with and without mathematical disabilities (MD). Experiment 1 examined the relationship between strategy knowledge, verbal WM, and visual-spatial WM in children with MD as a function of initial, gain, and maintenance conditions. The results showed that after partialing the influence of reading, stable strategy choices rather than specific strategy knowledge was related to verbal and visual-spatial WM span in high demand (maintenance) conditions. Experiment 2 compared children with MD to a group of chronological age-matched children and a group of math ability-matched children on the same conditions as Experiment 1. Age-matched children's verbal and visual-spatial WM performance was superior to that of children with MD, whereas WM performance was statistically comparable between children with MD and younger children matched on math ability. The selection of expert strategies was related to high WM span scores in the initial conditions. After controlling for reading achievement in a regression analysis, verbal and visual-spatial WM, stable verbal strategy choices, and expert strategy choices related to visual-spatial processing all contributed independent variance to math achievement. Overall, these results suggest that WM and math achievement are related to strategy knowledge. 相似文献

Reading to children has been advocated as a way to enhance language and literacy skills (A. G. Bus, M. H. van IJzendoorn, & A. D. Pellegrini, 1995). However, little is known about reading with children under age 3 (K. L. Fletcher & E. Reese, 2005), particularly in at-risk samples (A. van Kleeck, 2003). In the current study of 87 primary caregivers and their 24-month-old children enrolled in an early intervention program, we tested a theoretical model of the relations among 24-month-old children's language, caregivers' reported frequency of reading with children, and caregivers' reading strategies on children's language and attention using path models. Path models indicated that caregivers' use of expansions and questions with their 24-month-old children during reading was related to children's expressive language at 30 months. Caregivers' use of labeling, expansions, and questions was related to 24-month-old children's attention during reading. Although children's language skills at 24 months were associated with the reported frequency of caregiver reading in the home, only caregivers' use of questions had a relationship with frequency of reading. Reading practices that promote language development and engagement during reading observed in this at- risk sample have implications for reading intervention efforts with young children. 相似文献

Deaf children consistently lag behind their hearing cohorts in mathematics achievement tests. It has been hypothesized that their difficulty is a consequence of their lack of covert counting strategies and reliance on memorized verbal facts. We investigated the acquisition of an alternative method to solve sums, the signed algorithm, by six profoundly deaf primary school children. Similarly to the acquisition of the written algorithm by hearing children, deaf children's calculation errors with the signed algorithm were found to be systematic and related to the structure of the numeration system in British Sign Language. These results can be used to examine better ways of teaching arithmetic to deaf children and illustrate in a novel way the role of systems of signs in mathematical cognition. 相似文献

The goal of this study was to longitudinally examine relationships between early factors (child and mother) that may influence children's phonological awareness and reading skills 3 years later in a group of young children with cochlear implants (N = 16). Mothers and children were videotaped during two storybook interactions, and children's oral language skills were assessed using the "Reynell Developmental Language Scales, third edition." Three years later, phonological awareness, reading skills, and language skills were assessed using the "Phonological Awareness Test," the "Woodcock-Johnson-III Diagnostic Reading Battery," and the "Oral Written Language Scales." Variables included in the data analyses were child (age, age at implant, and language skills) and mother factors (facilitative language techniques) and children's phonological awareness and reading standard scores. Results indicate that children's early expressive oral language skills and mothers' use of a higher level facilitative language technique (open-ended question) during storybook reading, although related, each contributed uniquely to children's literacy skills. Individual analyses revealed that the children with expressive standard scores below 70 at Time 1 also performed below average (<85) on phonological awareness and total reading tasks 3 years later. Guidelines for professionals are provided to support literacy skills in young children with cochlear implants. 相似文献

This investigation was designed to determine whether an enactment interview condition involving a doll and props, in contrast to a verbal interview, would enhance 3- and 5-year-olds' (N = 62) recall of a pediatric examination. An additional aim was to explore the influence of behavioral styles and language skills on children's performance, and the extent to which these relations varied by age and interview condition. Both 1- and 6-weeks following their check-ups, the children in the enactment condition, particularly the 3-year-olds, provided more spontaneous, elaborate reports than did those assessed with a verbal protocol. Nonetheless, enactment also resulted in increased errors by the 3-year-olds at the first interview, and by children in both age groups after the 6-week delay. The age and interview condition effects, however, were moderated by the children's behavioral characteristics. Among the younger children, a measure of manageability predicted performance in the enactment setting, whereas an indicator of persistence was associated with recall in the verbal condition. The results have implications for an understanding of children's memory of events and of their ability to provide testimony in legal settings. 相似文献

OBJECTIVE: The aims of the present study were to investigate (1) whether young children with a known history of maltreatment by caregivers have more problematic peer relationships and classroom behaviors than other children, and (2) if children's behaviors with peers mediated associations between maltreatment and children's problem peer relations. METHOD: Participants included 400 young children (ages 4-8, M age=6.6), and 24 teachers in 22 schools. Six percent of children had a known history of maltreatment. Multiple methods (ratings and nominations) and reporters (children and teachers) were utilized to obtain information on peer relationships. Teachers reported children's physical/verbal aggression, and withdrawn and prosocial behaviors. RESULTS: Young children were able to nominate and rate whom they liked versus disliked in their classes, and their reports were modestly correlated with teacher reports. Regardless of the reporter, maltreated children were significantly more disliked, physically/verbally aggressive, withdrawn, and less prosocial, compared with their classmates. Among all children, physical/verbal aggression, withdrawal, and prosocial behavior were associated independently with some aspect of peer status. Maltreatment had indirect associations with peer likeability and peer rejection via maltreated children's relatively higher levels of physical/verbal aggression and, in some cases, withdrawal and relatively lower prosocial behavior. Maltreatment had an indirect association with teacher-reported peer acceptance via children's withdrawal. CONCLUSIONS: Findings indirectly associate early family experiences with problems in peer relationships, especially lower peer likeability and more rejection, via children's behaviors with peers. The finding that linkages exist even in the very earliest years of school highlights the need for very early home- or school-based efforts focused on improving behavior and relationships of maltreated children and others children with similar profiles. 相似文献

The correspondence between self-reported child-rearing attitudes and practices and actual child management was examined among 68 mothers of young children. Data on mothers' verbal and physical control techniques along with children's responses (cooperation vs. resistance) were obtained during 90 min of spontaneous interaction in a naturalistic setting. Self-report data (the Block Q-Sort) were obtained 1-2 weeks later. The Block Q-Sort factors were combined to represent authoritarian and authoritative patterns of attitudes. The authoritarian pattern was positively associated with the use of direct commands, physical enforcements, reprimands, and prohibitive interventions, and negatively associated with the use of suggestions. The authoritative pattern was positively related to the use of suggestions and positive incentives, and negatively related to the use of physical enforcements, prohibitive interventions, and direct commands. Mothers' enjoyment of the parental role and their negative affect toward the child, as expressed in the Block Q-Sort, were more a result of the child's cooperation/resistance during the interaction than predictors of maternal control strategies. 相似文献

Language delays, reading delays, and learning difficulties: interactive elements requiring multidimensional programming 总被引：1，自引：0，他引：1

Researchers have hypothesized four levels of instructional dialogue and claimed that teachers can improve children's language development by incorporating these dialogue levels in their classrooms. It has also been hypothesized that enhancing children's early language development enhances children's later reading development. This quasi-experimental research study investigated both of these hypotheses using a collaborative service delivery model for Grade 1 children with language difficulties from a socially and economically disadvantaged urban community in Australia. Comparing the end-of-year reading achievement scores for the 57 children who received the language intervention with those of the 59 children in the comparison group, the findings from this research are supportive of both hypotheses. The interrelationships between learning difficulties, reading difficulties, and language difficulties are discussed along with children's development in vocabulary, use of memory strategies and verbal reasoning, and the need for multidimensional programming. 相似文献

This study examined the nature of social conflict occurring spontaneously during children's play. Preschoolers' (mean age = 53.9 months) differential conflict behavior with their friends and acquaintances was analyzed by use of relationship status as a within-subjects factor. Children behaved differently when interacting with their friends than they did with acquaintances. Conciliatory gestures (e.g., compromise, apology) were used more often with friends than with acquaintances. Conciliatory gestures were more likely than yields to lead to peaceful outcomes. However, yields were used most often by the children. Yet, no matter what resolution strategy was used, friends were more likely to remain together after conflict than acquaintances were. Because friendships are important to them, children must learn ways to maintain interaction despite conflict. Conflict resolution strategies among peers begin to emerge in the preschool years, first within friendly relationships. It is suggested that rather than using direct intervention, teachers should indirectly facilitate the development of such strategies. 相似文献

This study explored inter- and intraindividual immigrant group differences in children's English verbal ability over ages 6-16 in 4 racial/ethnic groups-White Americans, Black Americans, Mexican Americans, and Puerto Ricans (N=2,136). Although all children's mean verbal scores increased with age, immigrant children (except for Black Americans) had lower scores than respective nonimmigrant children. In contrast, immigrant children (except for Mexican Americans) had more persistent verbal growth into adolescence than respective nonimmigrant children. Family resources moderately accounted for immigrant differences in children's mean verbal scores only. The findings support different theoretical models for understanding inter- and intraindividual immigrant differences in achievement. Mexican-American immigrants and Black American nonimmigrants were struggling and merit policy attention. 相似文献

The Development of Everyday Mathematics in Brazilian Children with Limited Formal Education 总被引：1，自引：0，他引：1

The sociocultural context in which children acquire and use everyday mathematics was studied in Brazilian shantytown communities. Children's developing mathematical abilities and use of currency in solving commercial problems were investigated. Interviews with the parents of 105 children from 4 to 14 years of age indicated that, when sent to make purchases at local stands, the problems entailed in the responsibilities parents assigned to children involved greater arithmetical complexity with increasing age. Children's accuracy and strategy use on arithmetic tasks similar to the problems encountered in commercial transactions revealed: ( a ) many children used currency to aid their problem solving; ( b ) with increasing age, currency use declined; and ( c ) children's currency use progressed from global estimates to the mental decomposition and manipulation of currency values. The mathematical complexity of children's commercial transactions correlated significantly with their mathematics performance even when age, grade in school, and years of schooling were statistically controlled The results provide evidence that by adjusting the mathematical complexity of children's commercial transactions, parents facilitate connections between children's developing competence and their everyday activities. 相似文献

Trends in family formation during the past several decades have increased children's exposure to mothers' partnership instability, defined as an entrance into or exit from a coresidential union or a dating partnership. Instability, in turn, is associated with negative outcomes for children and adolescents. This study uses data from the Fragile Families and Child Wellbeing Study to examine associations between mothers' partnership instability and children's school readiness, differences between coresidential and dating transitions, and the moderating role of child gender. Mothers' partnership transitions are negatively associated with children's verbal ability and positively associated with boys' behavioral problems at age five. In general, coresidential and dating transitions have similar effects on school readiness. The findings have important implications for our understanding of the growing gender gap in educational attainment. 相似文献

Children often learn new problem-solving strategies by observing examples of other people's problem-solving. When children learn a new strategy through observation and also explain the new strategy to themselves, they generalize the strategy more widely than children who learn a new strategy but do not explain. We tested three hypothesized mechanisms through which explanations might facilitate strategy generalization: more accurate recall of the new strategy's procedures; increased selection of the new strategy over competing strategies; or more effective management of the new strategy's goal structure. Findings supported the third mechanism: Explanations facilitated generalization through the creation of novel goal structures that enabled children to persist in use of the new strategy despite potential interference from competing strategies. The facilitative effect of explanation did vary with children's age and did not vary between explanations children created by themselves versus explanations they learned from the experimenter. 相似文献

The present study examines private speech and strategy-use patterns for solving simple number fact problems in addition. The progressive differentiation by grade between children's levels of private speech internalization--including silence--was investigated and related to children's developmental patterns for subcategories of strategy-use internalization. Comparisons were made between 67 children with math difficulties (MD) and 67 children without MD from Grade 2 to Grade 7 in primary schools. Two separate laboratory investigations were performed for each child to examine private speech and strategy-use internalization. Analysis was based on private speech category differences, strategy-use differences, and differences in the occurrence of private speech-strategy-use combinations. Children without MD showed a grade-determined shift from less to more internalized private speech and from the use of backup strategies to retrieval strategies. In contrast, the private speech and the strategy-use internalization of children with MD, reflected in inaudible private speech and backup strategy use, seemed to converge at earlier developmental levels. The development of children with MD seemed almost to stop at the inaudible private speech-backup strategy combination level. The silence-retrieval strategy combination level was the primary alternative for typical math achievers. In all, the characteristics of the development curves of the children with MD were consistent with a developmental difference and not with a developmental delay model. Implications for intervention and future research methodology are discussed. 相似文献

Black and white male schoolchildren covertly evaluated their own performance at a verbal task administered by black and white male experimenters. It was hypothesized that academically successful children would be predisposed to appraise themselves favorably, whereas relatively unsuccessful pupils would be biased toward self-criticism. The covert self-evaluations were assumed to represent at internalization of early experiences of predominantly positive or negative social reinforcement from adult socializing agents. The predicition for self-criticism was upheld in the white experimenter condition but not in the black experimenter condition. Relationships consistent with the theory were found between subjects' self-appraisals and their retrospective reports of positive and negative reinforcements received from parents and teachers in various typical situations. These relationships were more evident for black subjects than for white subjects. The extent to which children's self-praise and self-criticism mediated affect was assessed by means of a color conditioning technique. Contrary to predicition, possibly due to the easy nature of the experimental task. 相似文献
